Siemens SCALANCE OpenSSL NULL Pointer Dereference (CVE-2023-0216)

high Tenable OT Security Plugin ID 501879

Synopsis

The remote OT asset is affected by a vulnerability.

Description

An invalid pointer dereference on read can be triggered when an application tries to load malformed PKCS7 data with the d2i_PKCS7(), d2i_PKCS7_bio() or d2i_PKCS7_fp() functions. The result of the dereference is an application crash which could lead to a denial of service attack. The TLS implementation in OpenSSL does not call this function however third party applications might call these functions on untrusted data.

This plugin only works with Tenable.ot.
